Embodied-carbon rules assume a reuse market exists. LEED v5 made it a requirement, Buy Clean programs assume it, and specifiers write it into contracts. Almost nobody has checked whether the economics work.
New York City Economic Development Corporation is now checking. On August 25 it launched a year-long Circular Construction Hub pilot at MADE Bush Terminal, a 20-acre adaptive-reuse campus at 13 42nd Street in Sunset Park.
What the pilot actually does
Our Temenos, a Brooklyn M/WBE firm, will run recovery, sorting, storage and redistribution of selected construction materials. NYCEDC will track material intake, handling and resale, which is the data that has been missing from every circular-construction argument made in this city.
The point isn’t to prove reuse is virtuous. It’s to find out whether a load of salvaged material can be recovered, stored and resold at a price a small contractor will pay, and what citywide storage and reprocessing infrastructure would be needed to do it at scale.
Founder Rosemarie Miner described the hub as a hyperlocal resource for small construction businesses dealing with volatile supply chains. That framing is more honest than the carbon framing. A sub with a $400,000 job doesn’t have the working capital to ride out a materials price spike, and a nearby yard with usable stock is a hedge.
The pipeline behind it
Our Temenos came out of NYCEDC’s Waterfront Pathways Program and the ConstructNYC Green Training circular-construction module, a 39-hour course. The hub is the first award under the agency’s Ideas for Impact REOI, and it sits inside a 200-acre Sunset Park green-economy district that DSNY, AIA New York and The Durst Organization have all been involved with.
The number that will decide it
Deconstruction costs more than demolition, and always will. Labor to remove material intact is the whole difference. For a reuse market to clear, the resale price plus the avoided tipping fee has to beat that gap, and in most U.S. cities it doesn’t.
New York has unusually high tipping fees and unusually expensive material. If it doesn’t pencil here, it doesn’t pencil anywhere, and a year of intake data will say so one way or the other.
The city is testing the demand side elsewhere too. The Bronx Museum renovation is running a deep-energy retrofit on a 1962 masonry building under the same 80×50 capital program, and projects like it are where salvaged material would have to find a buyer.
